Joshua is 1.45 meters tall. At 2 p.m., he measures the length of a tree's shadow to be 31.65 meters. He stands 26.2 meters away

Lena [83]

Answer:

The height of the tree=8.42 m

Step-by-step explanation:

We are given that

Height of Joshua, h=1.45 m

Length of tree's shadow, L=31.65 m

Distance between tree and Joshua=26.2 m

We have to find the height of the tree.

BC=26.2 m

BD=31.65m

CD=BD-BC

CD=31.65-26.2=5.45 m

EC=1.45 m

All right triangles are similar .When two triangles are similar then the ratio of their corresponding sides are equal.

$\triangle ABD\sim \triangle ECD$

$\frac{AB}{EC}=\frac{BD}{CD}$

Substitute the values

$\frac{AB}{1.45}=\frac{31.65}{5.45}$

$AB=\frac{31.65\times 1.45}{5.45}$

$AB=8.42m$

Hence, the height of the tree=8.42 m

The school production of 'Our Town' was a big success. For opening night, 392 tickets were sold. Students paid $3.00 each, w

elixir [45]

Answer:

239 students and 153 non-students attended to the school production of "Our Town"

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Number of tickets of the school production sold = 392

Student ticket cost = US$ 3

Non-students ticket cost = US$ 5

Total collected = US$ 1,482

2. How many students and how many non-students attended?

For answering the question we will use the following equation:

x = Number of students that attended the school production

392 - x = Number of non-students that attended the school production

3x + (392 - x) * 5 = 1,482

3x + 1,960 - 5x = 1,482

-2x = 1.482 - 1,960

-2x = - 478

x = -478/-2

x = 239 ⇒ 392 - 239 = 153

239 students and 153 non-students attended to the school production of "Our Town"

Moving forward a negative distance is the same as moving backward a positive distance.

creativ13 [48]

The answer is: False, because, by definition, the distance (which is a scalar quantity) is the absolute value of the displacement. This means that the distance cannot be negative, but the displacement (which is define as a vector quantity can be positive or negative.
